ABSTRACT:
In a preferred embodiment, an accelerometer sensor system, having a first axis of rotation at a first given frequency of periodic oscillation thereabout, which accelerometer sensor includes: a first acceleration sensor; a platform to which the first acceleration sensor is fixedly attached; and the first acceleration sensor being vertically displaced from the first axis of rotation by a first selected distance such that the noise received by the first acceleration sensor, due to the periodic oscillation at the first frequency, is reduced.
